NTSB spokesman Chris O’Neil said investigators did not know what caused the battery fire in this week’s crash.

He said the agency was investigating because there was a post-crash fire involving an electric vehicle.

Earlier this month, Tesla and the NTSB got into an open feud over Tesla’s release of information from the probe into the Mountain View crash.

The agency said it booted Tesla out of a group investigating the crash after the company prematurely made investigation details public.

Tesla, however, disputed the claim. The company said it withdrew from the investigation agreement after being told it would be kicked out if it made additional statements before the NTSB finished its probe in the next 12 to 24 months.

Mr O’Neil said that despite the previous dispute, Tesla would be invited to be a party to the investigation of the Fort Lauderdale crash.

Tesla has been contacted for comment.

The NTSB normally makes recommendations to other federal agencies such as the National Highway Traffic Safety Administration, which has authority to impose regulations and seek recalls.
